Easy-to-use DAF/FAF device for face-to-face conversations or telephone calls.
Many states provide the Basic Fluency System free to qualified residents. (The device is called the Telephone Fluency System when provided by state programs.)
Altered Auditory Feedback Features
The Basic Fluency System provides two types of altered auditory feedback:
Delayed auditory feedback (DAF) immediately reduces stuttering about 70% at normal speaking rates without training, mental effort, or abnormal-sounding or abnormally slow speech. 55% carryover fluency after removing the device, without speech therapy. With speech therapy, DAF can induce a slower speaking rate with stretched vowels to make even severe stutterers nearly 100% fluent.
Frequency-shifted auditory feedback (FAF) immediately reduces stuttering at normal speaking rates. Only Casa Futura Technologies stuttering treatment devices have octave-scale FAF downshifting (pitch shifting) to induce vocal fold relaxation, training the user to no longer need the device.
Anti-Background Noise Features
Noise-canceling directional microphone eliminates background noise at the source.
High-frequency filters remove background noise above the user's vocal range.
Dynamic expansion makes loud sounds (e.g., the user's voice) louder and quiet sounds (e.g., other people's voices) quieter.
Quarter-octave FAF effectively reduces stuttering yet is acoustically transparent if the device picks up background noise.
Other Features
The Basic Fluency System plugs into telephones. You hear your voice and the caller's voice in both ears; the caller hears your normal voice. Leave your Basic Fluency System plugged into your telephone and practice speech therapy on every call. (Not compatible with Nokia cellphones.)
Binaural (two ear) or monaural (one ear) sound. Binaural sound is 25% more effective than monaural sound and is recommended for severe stutterers; mild stutterers can get by with monaural sound.
35-7500 Hz frequency range clearly reproduces all vocal frequencies of adults and children.
9-volt battery last about 15 hours. AC adapter (included) doesn't charge the battery.
Removable belt clip.
Beige case.
Two 3.5mm jacks for any standard microphone and headphones. One 2.5mm jack for any standard cellphone earset (except Nokia).
4.5" x 2.7" x 0.9" (11.5 cm x 7 cm x 2 cm); about the size of an iPod.
